RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.12/237,319, filed Sep. 24, 2008, which claims the benefit of U.S.Provisional Patent Application No. 60/975,096, filed Sep. 25, 2007, andU.S. Provisional Patent Application No. 61/096,596, filed Sep. 12, 2008,the contents of each of which are herein incorporated by reference intheir entirety.

BACKGROUND OF THE INVENTION

Mental disorders generate serious problems for the affected people,their families, and society. Currently, psychiatrists andneurophysiologists treat these disorders with a variety of medications,many of which have significant negative side effects.

Repetitive Transcranial Magnetic Stimulation (rTMS) uses anelectromagnet placed on the scalp that generates a series of magneticfield pulses roughly the strength of an MRI scan. Some studies haveshown that rTMS can reduce the negative symptoms of schizophrenia anddepression under certain circumstances. To generate low frequencymagnetic field pulses using an electromagnet such as in rTMS requireshigh current. Over time, this high current results in significant heatthat must be actively dissipated.

FIG. 4 shows an exemplary device in which the magnet 2 rotates so thatthe plane of rotation is generally perpendicular to the surface of thescalp of a subject 6 and a bio-feedback sensor and/or EEG electrode 82 ais used to control the speed of rotation about the rotation axis 36. Therotation of the magnet 2 is driven by a motor 72 which is coupled to adrive shaft 4, and the drive shaft 4 is coupled to the magnet 2. In someembodiments at least two EEG electrodes, 82 a, 82 b are used to controlthe speed of rotation, wherein at least one EEG electrode, for exampleEEG electrode 82 b, is used as a reference electrode (and/or a groundelectrode). The electrodes, 82 a, 82 b may be connected to an amplifier80 which can amplify the signal received from the electrodes, 82 a, 82b. The magnet rotation may be controlled and/or monitored by acontroller subunit (controller), 58, which may also receive, record,and/or display the signal or signals received from the EEG electrodes 82a, 82 b. In some embodiments, the reading from a reference EEGelectrode, for example EEG electrode 82 b, is subtracted and/orotherwise removed from the reading from the second EEG electrode, forexample EEG electrode 82 a. In some embodiments, the bio-feedbacksensor/EEG electrode is used, at least in part, to determine thesubsequent treatment regimen for the subject.

In some embodiments, the EEG electrodes are used to measure the brainwaves of the subject at various times, for non-limiting example, priorto applying a method of treatment as provided herein using a devicedescribed herein, during application of a method of treatment asprovided herein using a device described herein, and/or after applying amethod of treatment as provided herein using a device described herein.In some embodiments, the EEG electrodes are used to measure the brainwaves of the subject at various times, for non-limiting example, priorto using a device described herein, during use of a device describedherein, and/or after using a device described herein. In someembodiments, the EEG electrodes are used to measure the brain waves ofthe subject continuously for a specified period of time. In someembodiments the specified period of time is for non-limiting example, atleast about one hour, at least about 45 minutes, at least about 40minutes, at least about 30 minutes, at least about 20 minutes, at leastabout 15 minutes, at least about 10 minutes, at least about 5 minutes,at least about 1 minute, at least 30 seconds, at least about 10 seconds,at least about 5 seconds, and at least about 1 second.

In some embodiments, alpha EEG of abrain of a subject can be critical in normal cognitive processes and thedesynchronization of alpha activity can play a pathophysiological rolein the mental disorders listed above. In some embodiments, the therapyusing methods or systems described lasts for about 20 minutes, is verygentle, and unnoticeable to the subject.

The therapy using methods or systems described can be mildenough to be used every day or as needed. The therapy using methods orsystems described does not have to involve any medication whatsoever.

“Patient” and “subject” are synonyms, and are used interchangeably. Asused herein, they mean any animal (e.g. a mammal) on which theinventions described herein may be practiced. Neither the term “subject”nor the term “patient” is limited to an animal under the care of aphysician.

FIG. 5 shows a sample EEG segment for a subject before therapy isdelivered. The block on the left shows a time series EEG while thesubject is sitting at rest with eyes closed. The block in the centershows the energy across the frequency spectrum for the sampled EEG. Thevertical line drawn through the peaks is at 9.1 Hz, the subject'sintrinsic alpha frequency. The circle at the right shows thedistribution of EEG energy at the intrinsic alpha frequency throughoutthe head, looking down on the top of the subject's head. In the circlerepresentation, the majority of the EEG energy at the alpha frequency isconcentrated at the back of the brain.

FIG. 6 is similar to FIG. 5, except the EEG was sampled immediatelyfollowing therapy. In this, it can be seen that the energy associatedwith the intrinsic alpha frequency has increased significantly. From thecircle representation on the right, it can be seen that the distributionof energy at the intrinsic alpha frequency throughout the head is moreuniform, though the majority of energy is still concentrated at the backof the brain.

In some embodiments, devices described can comprise a substantiallyplanar member upon which are affixed a plurality of magnets. Thus, themagnets may be oriented so as to permit application of a magnetic fieldhaving a substantially uniform polarity to a user. In some embodiments,the magnets may also be positioned on the array so that adjacent magnetshave opposite polarities.

In some embodiments, the devices described may be configured so as torestrict, in one or more directions, the movement of the magnet withinthe devices, thereby enabling selection of the polarity of the magneticfield to which the user is subjected. For example, magnets may be placedwithin the devices described so that one face of the magnet is alwayspointing toward a head of a subject. Accordingly, the subject issubjected to a dynamic magnetic field having a specific polarity.

In some embodiments, the devices described comprise at least onerotating mechanism. In some embodiments, mechanical subunits includingcams, gears and/or linkages may be utilized to move at least one magnet.These mechanical subunits may be powered through motorized means or maybe connected to other devices moving in the surrounding environmentwhich will cause the mechanical device to move the magnet. An externalexciter magnet may be positioned near the devices described, where theexternal exciter magnet generating a sufficiently strong magnetic fieldto cause movement of at least one magnet contained within the devicesdescribed.

In some embodiments, magnets of the devices described can be rotated bya rotating mechanism other than a motor. In some embodiments, thedevices comprise at least one orifice so that a stream of fluid such asa gas or liquid may be forced into the devices, wherein the stream offluid being sufficiently strong so as to move at least one magnet, thuscreating relative movement between the at least one magnet and a head ofa subject.

While permanent magnets of any strength may be utilized for the methodsand devices described herein, generally magnets having strengths withinthe range of about 10 Gauss to about 4 Tesla can be used. In someembodiments, the strength of at least one permanent magnet is from about100 Gauss to about 2 Tesla. In some embodiments, the strength of atleast one permanent magnet is from about 300 Gauss to about 1 Tesla.

In some embodiments, the permanent magnets for the methods and devicesdescribed comprise rare earth magnets such as neodymium, iron, boron orsamarium cobalt magnets. In some embodiments, the permanent magnets forthe methods and devices described are neodymium iron boron magnets. Insome embodiments, ceramic magnets, electromagnets or other more powerfulmagnets may be utilized as they become available. In some embodiments,electromagnets may be utilized for the methods and devices described.Current can be supplied to the electromagnet by wires penetratingthrough the devices described and connecting to an external powersource.

Described are magnetic therapeutic devices and methods for magnetictherapies where a brain of a subject is subject to at least one dynamicmagnetic field having an amplitude of at least a half waveform. Incertain embodiments, the treatment area is exposed to a half waveform ofmagnetic flux. In other embodiments, the treatment area is exposed to afull waveform of magnetic flux. Still other embodiments may permittreatment area to be exposed to either a half or full waveform. Tosubject the treatment area to such a dynamic magnetic field, themagnetic source may be rotated, oscillated, moved through a particularpattern, or otherwise moved relative to a head of a subject. Theapplication area of the subject can be positioned relative to themagnetic source so that the magnetic field extends around and/or throughthe application area. In certain embodiments, the devices describedcomprise at least one magnet having a north and south magnetic pole anda pole width equal to the width of the magnet at the poles.

Three parameters of magnetic fields generated by the devices describedcan be manipulated:

-   -   (a) the intensity of the magnetic field at the treatment site,        which can be determined by the strength of the magnets used and        the distance between the magnets and the subject's head;    -   (b) the frequency of the magnetic field, i.e., the rate of        change of the magnetic field, which can be determined by        movements of at least one magnet, such as by varying the speed        at which at least one magnet moved relative to the application        area;    -   (c) the amplitude of the net change in magnetic flux (or        waveform) to which the application area is subjected, and    -   (d) the phase of the magnetic field between two (or more)        magnets (i.e. the magnetic phase) when the magnetic field        frequencies of the two (or more) magnets are the same (or        substantially the same).

As to the amplitude of the net change in magnetic flux, it is generallyknown that permanent magnets have a north pole and south pole, withnorth pole magnetic flux emanating from the north pole, and south polemagnetic flux emanating from the south pole. In some embodiments, theapplication area is subject to a “full waveform” according to thedevices and methods described. For example, when a permanent magnetrotates relative to an application area, the application area mayinitially be subjected to a “full north pole field” where the north poleof the magnet is closest to the application area. As the north polerotates away from the application area and the south pole rotates towardthe application area, the strength of the north pole field decreasesuntil a “neutral field” is encountered, approximately at the midpoint ofthe magnet. As the south pole continues to rotate toward the applicationarea, the application area is subjected to a south pole field ofincreasing intensity until the south pole is closest to the applicationarea where the application area is subjected to a “full south polefield.” By rotating in this fashion, the object is subjected to a “fullwaveform.” Likewise, the application area is also subject to a “fullwaveform” when the magnet rotates from the south pole to the north pole.As used herein, a south pole may also be referred to as “negative,” (−),or S, and a north pole may also be referred to as “positive,” (+), or N.

For example, FIG. 10A through FIG. 10G show some exemplary embodimentsfor various movements of at least one permanent magnet. FIG. 10A shows agraph of the magnetic field over time. That is, it shows a graph 92 aexpressing an example magnetic field experienced by a subject 6 a as amagnet 2 a rotation about an axis between the north pole (+) and southpole (−) of the magnet 2 a. The position of the magnet relative to thesubject 6 a and the field strength (+ or −, amplitude can vary,depending on for example, the application, method, magnet and therapybeing delivered) is shown in FIG. 10A. For example at Time=0, thesubject 6 a may experience no magnetic field (i.e. a neutral field) whenthe magnet's north pole is equally as far from the subject 6 a as themagnet's south pole (assuming the north pole and south pole have equalstrengths yet opposite polarities). As the magnet 2 a spins such thatthe south pole of the magnet 2 a is closest to the subject 6 a, thesubject 6 a experiences a negative magnetic field, as shown in FIG. 10a, and as the magnet 2 a spins further, the subject 6 a is exposed to achanging magnetic field from, for example, a neutral field, to anegative field, to a neutral field, to a positive field, and so on. Asfurther shown in FIG. 10A, an array of magnets (i.e. a plurality) may beused alternatively to a single magnet to provide a more uniform field tothe subject's brain. FIG. 10A shows a subject 6 a 1 exposed to an arrayof nine rotating magnets, as well as a subject 6 a 2 exposed to an arrayof five rotating magnets. In some embodiments, any number of rotatingmagnets may be used to provide a more uniform field to the subject'sbrain.

Various exemplary wave forms resulting from embodiments of the devicesand methods provided herein are shown in FIG. 10B through FIG. 10G. Forexample, FIG. 10B shows a full waveform in the form of a step functionwhere a magnetic field cycles through a sequence wherein the magneticfield is positive (+) then neutral, then negative (−), then neutral, andrepeats. FIG. 10C shows a half waveform in the form of a step functionwhere a magnetic field cycles through a sequence wherein the magneticfield is positive (+) then neutral, and repeating this sequence. FIG.10D shows an alternative a half waveform in the form of a step functionwhere a magnetic field cycles through a sequence wherein the magneticfield is positive (+) then off (or neutral), remaining off (neutral) fora longer period of time than remaining positive (+), and repeating thissequence. FIGS. 10E, 10F and 10G each show example full wave formsresulting from embodiments of a NEST device having at least one magnetwherein the magnet's, or magnets' north pole and south polealternatively change distances from the subject in a regular pattern. Byshielding a pole of the magnets of the array, half waveforms may becreated using the same array of magnets, for example shielding as shownin FIG. 11C and/or FIG. 11D, discussed further below.

In some embodiments, the application area is subject to a “halfwaveform” according to the devices and methods described. For example,an object may be subjected to a “half waveform” where the magnet rotatesrelative to the application area from a full north pole field to aneutral field or from full south pole field to a neutral filed. In someembodiments, the “half waveform” treatment can be achieved by limitingrotation or movement of the magnets. In some embodiments, the “halfwaveform” treatment can be achieved by shielding the north pole or southpole of the magnet, leaving only the other pole exposed for thetreatment of the application area.

To subject the treatment area to a dynamic magnetic field by the methodsand devices described herein, the magnetic source may be rotated,oscillated, moved through a particular pattern, or otherwise movedrelative to the treatment area. In some embodiments, the magnetic sourceis rotated about an axis. In some embodiments, the magnetic source isoscillated with respect to the application area. In some embodiments,the magnetic source has a linear movement with respect to theapplication area. Such linear movement can be like a piston movement. Insome embodiments, the magnetic source has a swing motion with respect tothe application area. Such swing motion can be like a swinging pendulummovement. In some embodiments, the magnetic source has a combination ofrotation, linear, oscillated, and swing movements. In some embodiments,the magnetic source has any combination of rotation, linear, oscillated,and swing movements. In some embodiments, said movement comprises atleast one of rotational motion, linear motion, and swing motion.

In some oscillatory embodiments, a plurality of magnets are fixedlymounted on a supporting plate, the magnets being spaced apart from eachother so that the each magnet is spaced apart from the next nearestmagnets by at least one pole width. Each magnet may be positioned sothat the upwardly facing pole of each magnet is the same. For example,in one configuration, the north pole face of each magnet is mounted to asupporting plate. In an alternate configuration, the south pole face ofeach magnet is mounted to a supporting plate. By laterally displacingmagnets so arranged proximate to an application area, such area issubjected to a repeating half waveform (full north to zero to fullnorth). In another embodiment, by reversing the polarity of the magnetsproximate to the application area, such area is subjected to a repeatinghalf waveform (full south to zero to full south).

In some oscillatory embodiments, a plurality of elongated magneticsources are placed adjacent to each other so that a repeating pattern ofalternating magnetic poles are formed, the poles being spaced apart by apredetermined distance. The oscillation of the magnetic sources by adistance equal to or greater than the predetermined distance subjects anapplication area to a complete reversal of magnetic flux, i.e., a fullwaveform.

FIGS. 11A through 11L show additional exemplary embodiments for variousmovements of at least one permanent magnet. FIG. 11A shows two magnets102 a 1, 102 a 2 coupled to each other and spun about a rotation axis138 a. In the embodiment of FIG. 11A, the subject (not shown) could bepositioned, for example, such that the rotation axis 138 is generallyperpendicular with the scalp of the subject, or wherein the rotationaxis 138 is generally parallel to the scalp of the subject, depending onthe desired waveform and/or magnetic flux for the particular subject.FIG. 11B is similar to FIG. 11A but with the magnets 102 b 1, 102 b 2having opposite polarity to the magnets 102 a 1, 102 a 2 of FIG. 11A.

In the shown embodiment, thesouth pole (S) of the magnet 102 e is farther from the pendulum pivot 96than the north pole (N) of the magnet 102 e. In the embodiment of FIG.11E, the subject (not shown) could be positioned, for example, such thatthe pendulum path 198 is generally perpendicular with the scalp of thesubject, or wherein the pendulum path 198 is generally parallel to thescalp of the subject, depending on the desired waveform and/or magneticflux for the particular subject. FIG. 11F has similar characteristics toFIG. 11E, but with the magnet 102 f of FIG. 11F having opposite polarityto magnet 102 e of FIG. 11E.

FIG. 11G depicts another embodiment device having a single magnet 102 gthat is configured to spin about a rotation axis 138 positioned in thenorth pole region of the magnet 102 g (i.e. somewhere between theneutral plane of the magnet and the north pole (N) end of the magnet 102g). The rotation axis 138 is generally parallel to the neutral plane(not shown) of the magnet 102 g. In the embodiment of FIG. 11G, thesubject (not shown) could be positioned, for example, such that therotation axis 138 is generally perpendicular with the scalp of thesubject, or wherein the rotation axis 138 is generally parallel to thescalp of the subject, depending on the desired waveform and/or magneticflux for the particular subject. FIG. 11H is similar to FIG. 11G butwith the magnet 102 h having opposite polarity to the magnet 102 g ofFIG. 11G, and wherein the rotation axis 138 positioned in the south poleregion of the magnet 102 h (i.e. somewhere between the neutral plane ofthe magnet and the south pole (S) end of the magnet 102 h).

FIG. 11I shows another embodiment device having a single magnet 102 jmounted a distance away from the rotation axis 138 of the device, andhaving the north pole (N) of the magnet 102 j closer to the rotationaxis 138 than the south pole (S) of the magnet 102 j. In the embodimentof FIG. 11I, the subject (not shown) could be positioned, for example,such that the rotation axis 138 is generally perpendicular with thescalp of the subject, or wherein the rotation axis 138 is generallyparallel to the scalp of the subject, depending on the desired waveformand/or magnetic flux for the particular subject. FIG. 11J is similar toFIG. 11I but with the magnet 102 k having opposite polarity to themagnet 102 j of FIG. 11I.

FIG. 11K depicts an alternate embodiment device having a single arc-likemagnet 102 l (which may be, for example, a horseshoe magnet), that iscoupled to a drive shaft 104 aligned with the rotation axis 138. As thedrive shaft 104 spins about the rotation axis 138, the magnet 102 llikewise rotates about the rotation axis 138. In the embodiment of FIG.11K, the subject (not shown) could be positioned, for example, such thatthe rotation axis 138 is generally perpendicular with the scalp of thesubject, or wherein the rotation axis 138 is generally parallel to thescalp of the subject, depending on the desired waveform and/or magneticflux for the particular subject.

The phrase “continuously applied” or “continuous application” refer totreatments where an application area is subject to at least one magneticfield with a full waveform or a half waveform for a period of timetypically longer than 2 minutes. Such phrases are distinguished fromshort pulse application (typically microseconds) of a magnetic field.

In some embodiments, the devices described can be powered with arechargeable battery. One battery charge can be enough for one or moretherapy sessions. In some embodiments, a display can indicate batterylife remaining and signal when the device should be recharged.

In some embodiments, the devices described use at least one connectionto a computer to allow for upload of therapy information, download ofsoftware upgrades, and to order more sessions to be allowed for thedevice. The connection may be a USB type of connection, or another typeof connection known or contemplated.

The speed of rotation can be critical to the specific therapy that isdelivered. Therefore, in some embodiments, the speed of rotation istightly controlled. In some embodiments, the speed setting may be set bythe user or may be set by a controller that uses a biological sensor asfeedback to optimize the magnetic field frequency.

In some embodiments, the methods and devices described use at least onebio-feedback sensor, the sensor can be an EEG lead placed on the scalp,along with a reference electrode that can be placed in an area of littlesensed brain activity. When more than one EEG sensor is used,correlation information can be gained among separate areas of the brain.The EEG and reference leads can be connected through a differentialamplifier to a controller module that regulates the speed of at leastone motor to rotate at least one magnet above the scalp.

Sensing EEG with a magnet rotating in the vicinity can be difficult,since the magnet can affect the electrode. To allow proper EEGmeasurement, a technique may be used to subtract the pure sine wave fromthe sensed EEG. In some embodiments, the magnet rotation can be stoppedtemporarily in order to take an EEG measurement that does not includethe effect of the rotating magnet.

Provided herein is a device operable to influence an EEG phase betweentwo sites in the brain of a subject 2806 within a specified EEG band,for example, as shown in FIG. 28. Any of the devices described hereinmay be used to influence the EEG phase between two sites in the brain ofa subject within a specified EEG band. The device may comprise at leasttwo permanent magnets 2802 a, 2802 b, wherein the subunit (not shown inFIG. 28, but shown in other figures, for example, FIGS. 1-4, 24, 25, 27)of the device is coupled to both the first and the second magnet, andwherein the subunit enables movement of the second magnet at a frequencybetween about 0.5 Hz and about 100 Hz. The subunit may enable movementof the second magnet at a frequency between about 2 Hz and about 20 Hz.The subunit may enable movement of the first and second magnet at thesame frequencies.

FIG. 28 shows an example embodiment of a NEST device applied to asubject 2806, wherein the NEST device has three diametrically magnetizedcylindrical magnets 2802 a, 2802 b, 2802 c, rotating about theircylinder axes having a magnetic phase between at least two of themagnets that is not zero. As shown in FIG. 27. a first permanent magnet2802 a of a device operable to influence an EEG phase may have a firstrotational orientation relative to a treatment surface 2899 of thedevice and the second permanent magnet 2802 b may have a secondrotational orientation relative to the treatment surface 2899 of thedevice. The device may be operable to move the first permanent magnet2802 a at the same frequency as the second permanent magnet 2802 b.

In some embodiments, a magnetic field results from a first magneticsource and a second magnetic source. FIG. 29 shows the magnetic fieldstrengths 2997 a, 2997 b of two magnets moving at the same frequency atthe same time 2992, but having a magnetic phase 2991 relative to oneanother (out of phase relative to each other). The magnetic fieldstrengths in this graph are plotted with time on the x axis, andmagnetic field strength on the y axis (with two x axis, to show therelative field strengths of each magnet simultaneously). As depicted inFIG. 29, a first magnetic source and a second magnetic source may be outof phase relative to each other in order to influence the EEG phase ofthe subject. In some embodiments, the amount that the first magneticsource and the second magnetic source are out of phase relative to eachother is called the magnetic phase 2991. The magnetic phase may bemeasured peak to peak (i.e. peak of the first magnet's field strength topeak of the second magnet's field strength—as shown in FIG. 29, at2991), or trough to trough, or inflection to inflection, or any similarplot characteristic on both of the magnets' field strength graphs.

In some embodiments, the first portion of the treatment surface is theportion of the treatment surface approximately closest to the firstpermanent magnet, and wherein the second portion of the treatmentsurface is the portion of the treatment surface approximately closest tothe second permanent magnet. For example, in FIG. 28, the treatmentsurface 2899 extends between the magnets 2802 a, 2802 b, 2802 c and thehead of the subject 2806. The first portion of the treatment surface isthat portion of the treatment surface 2899 between the first magnet 2802a and the nearest portion of the head of the subject 2806, Likewise, thesecond portion of the treatment surface is that portion of the treatmentsurface 2899 between the second magnet 2802 b and the nearest portion ofthe head of the subject 2806. In some embodiments, the first portion ofthe treatment surface is the portion of the treatment surface closest tothe first permanent magnet that is intended to be approximatelytangential to the head of the subject nearest that treatment surface. Insome embodiments, the second portion of the treatment surface is theportion of the treatment surface approximately closest to the secondpermanent magnet that is intended to be approximately tangential to thehead of the subject nearest that treatment surface.

In some embodiments of the devices disclosed herein, the differencebetween the first rotational orientation and the second rotationalorientation results in a magnetic phase when the first permanent magnetis moved at the same frequency as the second permanent magnet. As shownin FIG. 28, for non-limiting example, the first magnet 2802 a has arotational orientation relative to the treatment surface 2899 that isdifferent than the rotational orientation of second magnet 2802 b.

The magnetic phase of the device may be operable to influence an EEGphase between a first site and a second site in the brain of a subjectof a specified EEG frequency. FIG. 30 shows theoretical EEG electrodereadings 3095 a, 3095 b measured at two locations on a subject's headwithin a single EEG band when the two locations are exhibiting similar(or the same) frequency, but are out of phase relative to each other,i.e. displaying an EEG phase 3089. The EEG readings over time in thisgraph are plotted with time on the x axis, and EEG readings on the yaxis (with two x axis, to show two EEG electrode readings takensimultaneously at different locations on the head of the subject). Asdepicted in FIG. 30, a first EEG reading 3095 a, and a second EEGreading 3095 b may be out of phase relative to each other. In someembodiments, the amount that the first EEG reading and the second EEGreading are out of phase relative to each other is called the EEG phase3089. The EEG phase 3089 may be measured peak to peak (i.e. peak of thefirst EEG reading to peak of the second EEG reading—as shown in FIG. 30,at 3089), or trough to trough, or inflection to inflection, or anysimilar plot characteristic on both of the EEG reading graphs.

The magneticfields (first magnetic field, and second magnetic field) may be of thesame frequency, but out of phase with each other.

Additional magnetic fields may be provided by additional means forapplying such magnetic fields. These too may be out of phase with eachother, or with any of the magnetic fields. Nevertheless, the magneticfields in some embodiments may have the same frequencies. The devicesmay be a Permanent Magneto-EEG Resonant Therapy (pMERT) (i.e. aNeuro-EEG Synchronization Therapy NEST device) as described herein.

Even a device having a magnetic phase of 0, where the magnets spin atthe same frequencies, and in-phase relative to the treatment surface ofthe device (and/or relative to the head of the subject), may influencethe EEG phase between two locations measured on the subject's head. Forexample, if prior to treatment, two EEG electrodes take EEG readingswithin an EEG band, and the frequencies are the same (or substantiallyso), however, the EEG readings have peaks for each electrode atdifferent times (i.e. a non-zero EEG phase), a device as describedherein may influence the EEG phase by applying a magnetic field having amagnetic phase (i.e. where the magnets move at the same frequency andin-phase with each other).

Such electrode placements and configurations may be part of anyNEST device described herein. Alternatively, these electrodeconfigurations (including placement and conformation) may be part of anydevice wherein a clearer EEG signal is desired, since theseconfigurations result in reductions in noise and reduced resistivityfrom other signals (such as muscle twitches, etc) as compared toelectrodes placed on, for example, the head of a subject.

While an anatomical location of substantially no electrical impulseinterference (but where brain activity may be measured) may provide aclearer EEG signal resulting in less noise and reduced resistivity fromthe skull, the first electrode may alternatively be placed on the scalp(either directly, and/or with hair between the scalp and the electrode).A single or a plurality of electrodes may be placed on the scalp forcoherence measurement, phase measurement, intrinsic frequencymeasurement, and/or Q-factor measurement. Noise from scalp movementand/or resistivity from the skull may be filtered from the signal (orsignals) received from the EEG electrodes, however, such filtering maynot be necessary. Curve smoothing may be applied to the signal (orsignals) received from the EEG electrodes, however, such curve smoothingmay not be necessary. Using any of the EEG recording means noted herein,multiple signal recordings may be taken and combined to determine, fornon-limiting example, a coherence measurement, an intrinsic frequencymeasurement, and/or a Q-factor measurement.

The area of the scalp upon which the first EEG electrode (or theplurality of electrodes) is/are placed may be induced to have lessmuscle activity, or it may naturally have less muscle activity thanother areas on the scalp. Inducing less muscle activity in the area ofthe scalp may be achieved in various ways. For non-limiting example, thearea may be relaxed by a muscle relaxation means such as an injectionwith a substance that relaxes (and/or paralyzes) the muscles in thearea, a topical application of a substance that relaxes (and/orparalyzes) the muscles in the area, and/or by an ingested musclerelaxation substance.

rTMS Therapy

Repetitive Transcranial Magnetic Stimulation (rTMS) refers to uses of amagnetic field administered in very short grouped pulses (microsecondsin length) to a patient's head to achieve a constant train of activationover brief periods of a treatment session. These brief magnetic fieldscan stimulate small areas of the brain non-invasively. During a singlesession, about 3,000 magnetic pulses can be given over an interval ofabout 30 minutes.

The short pulses of magnetic energy generated by rTMS devices canstimulate nerve cells of the brain, often at frequencies close tothresholds of exciting brain cells. Magnetic fields generated by rTMSdevices can pass through the skull and into the cortex without beingdistorted. The result is a very focal type of stimulation, minimizingstimulation of brain tissue not intended to be stimulated.

The magnetic pulses generated by rTMS devices are generally believed toinduce electrical charges to flow. The amount of electricity created inthe brain is very small, and can not be felt by the patient. Theseflowing electric charges can cause the neurons to fire or become activeunder certain circumstances. Typically, an objective of rTMS Therapy isto stimulate (or activate) brain cells.

(a) Frequency—Higher frequencies (>10 Hz) are believed to increasecortical excitability;(b) Intensity—As a percentage of the threshold at which motor activitycan be elicited (˜1-2 Tesla);(c) Duration—Pulse trains are brief (1-2 seconds), and intertrainintervals can be 30-60 seconds; and(d) Site of Stimulation—Depending on patient population or specificbrain functions.

In some embodiments, severity of psychosis, depression, and movementdisorders can be assessed with PANSS, Montgomery-Asberg DepressionRating Scale (MADRS), Barnes Akathisia Rating Scale (BARS), andSimpson-Angus Scale (SAS), as described by Jin Y et al. above. In someembodiments, severity of psychosis, depression, and movement disorderscan be assessed with the Hamilton Anxiety Scale (HAMA), the HamiltonDepression Scale (HAMD), or any methods known in the art. In someembodiments, efficacy in clinical ratings can be evaluated by usinganalyses of variance (ANOVA) as described by Jin Y et al. above. In someembodiments, raw EEG data can be edited offline by an experiencedtechnician who is blind to the treatment conditions to eliminate anysignificant or apparent artifact as described in Jin Y et al. above. Insome embodiments, multivariate analysis of variance (MANOVA) withrepeated measures can be used to determine the main effect interactionsas described in Jin Y et al. above.

EXAMPLES

The invention is described in greater detail by the followingnon-limiting examples.

Example 1

In some embodiments, described are devices that provide low frequencynear-sinusoidal TMS therapy by rotating at least one permanent magnet inclose proximity to the subject's head. The direction of rotationrelative to the subject can vary depending on the specific therapydesired. Also, the speed of rotation can be adjusted to provide theoptimal therapeutic benefit. The speed adjustment itself can come fromthe user of the device or from a controller that uses feedback from abio-sensor to determine the optimal speed.

In particular embodiments, a bar magnet can be mounted at the end of theshaft with the line through the poles perpendicular to the axis of theshaft. The shaft can be rotated by an adjustable motor. The magnet canrotate so that the plane of rotation is perpendicular to the surface ofthe scalp. Accordingly, the positive and negative poles of the magnetcan be alternately brought in close proximity to the scalp. This cancreate a near-sinusoidal magnetic field in the brain in which thelocation where the field is strongest is that which is closest to themagnet.

Example 2

In particular embodiments, a horseshoe magnet can be mounted at the endof the shaft with the poles positioned at the far end from the shaft.The shaft can be rotated by an adjustable motor, as in the previousexample. The magnet can be positioned above the subject's scalp suchthat the plane of rotation is parallel to the surface of the scalp.Accordingly, the positive and negative poles can rotate in a circlearound the scalp. This can create a sinusoidal magnetic field in thebrain in which the phase of the magnetic field is dependent on where themagnetic poles are in their rotation. In general, the magnetic fieldunder one pole will be of opposite polarity to the magnetic field underthe opposite pole.

Example 3

In particular embodiments, two bar magnets can be used, each mounted atthe end of a shaft. The shafts can be rotated by adjustable motors. Themagnets can be positioned on opposite sides of the subject's head, andthey are rotated synchronously to provide a more uniform phase for themagnetic field in the brain. When the north Pole of one bar magnet isnext to the subject's scalp, the south Pole of the other magnet will benext to the subject's scalp on the opposite side of the subject's head.

Example 4

In particular embodiments, the NEST (pMERT) device is a small, generallycube-shaped device with one side that is curved to allow contact withthe top of the subject's head. FIGS. 7-9 show the NEST (pMERT) device insuch embodiments, and also show the NEST (pMERT) device with a subjectlying on his/her back with his/her head resting in the device to receivetherapy.

FIGS. 7, 8, and 9 show an exemplary embodiment of the pMERT (NEST)device 88. In this embodiment, a button EEG electrode 82 a is located onthe concave surface of the device 88 and a second reference electrode 82b extends via a wire from the side of the device 88. The display 64 andcontrol buttons 86 (device controls) are located on top of the device 88to provide information and allow the user to adjust parameters and enterpatient data. A USB port 84 (which may also and/or alternatively be atleast one of an internet connection port, a power supply, a modemconnection, and another type of communications means) is located at thetop rear of the device 88, to allow it to be connected via a USB cableto a PC, allowing uploading of data and downloading of a dosage quota.FIG. 8 shows the pMERT (NEST) device 88 from FIG. 7 in which a subject 6is lying with his/her head against the concave surface of the device 88.At least one moving magnet is unseen inside the pMERT (NEST) device 88in order to deliver therapy to the subject 6. Moving magnets such asthose in configurations described herein may be used in the device 88shown in FIGS. 7, 8, and 9. The subject's head is pressed against thebutton EEG electrode (not shown), with the second electrode 82 battached to the subject's right ear. FIG. 9 shows an alternate angle ofthe subject 6 receiving therapy from the pMERT (NEST) device 88 asdescribed in FIG. 7 and/or FIG. 8.

In these particular embodiments, the pMERT as shown in FIGS. 7-9contains a single EEG lead (i.e. electrode) which is to be placed at thetop of the subject's head. Alternatively, multiple EEG electrodes may beused in recording and/or monitoring the subject's brain waves at leastone of before, during, and after the therapy is applied to the subject.The subject or nurse can prepare the EEG leads (and/or electrodes) withan electrolytic gel beforehand to lower the impedance. The referenceelectrode can be placed on the subject's ear. In some embodiments, thereading from a reference EEG electrode is subtracted and/or otherwiseremoved from the reading from the second EEG electrode.

When therapy is needed, the subject or nurse can follow the instructionson the display, which will provide a walkthrough of the EEG electrodepreparation. Once complete and the patient is situated in the device,the EEG is checked by the pMERT to ensure that the electrode is placedcorrectly. If not, an audible tone or instruction is given to allow thepatient to resituate himself/herself until proper contact is made.

Once contact is made, the patient lies still with eyes closed while thepMERT (NEST) acquires a representative EEG sample. The EEG data isanalyzed and, depending on the therapy to be delivered, the magnet ormagnets are rotated at the appropriate speed. The patient does not feelanything during the procedure, except for a diminution of the symptomsof the disorder, and perhaps a feeling of calm. During therapy, thedevice may sample the EEG data either by subtracting out the influenceof the magnet or by temporarily halting the magnet while the EEG data issampled. The display is used to show time remaining and any othernecessary status information for the device. After the therapy time, themagnet stops and a second EEG is taken, to be compared to the first EEG.Upon completion of the second EEG acquisition, an audible signal isgiven to indicate end of therapy.

Example 5 Purchasing Dosage Quotas and Report Generation

The methods and devices described are intended to be used bypsychiatrists/therapists to treat patients with mental disorders.Psychiatrists who take advantage of this therapy can register accountswith a vendor of the devices described and be given a username andpassword. When a psychiatrist sees a patient with a disorder and thepsychiatrist feels that the patient could benefit from the methods ordevices described herein, the psychiatrist either orders a device orselects one that has been pre-purchased.

The psychiatrist (or administrative assistant) can plug a pMERT (NEST)device into a USB port on a PC connected to an interne. Using web accessand their username/password, the psychiatrist can login to the NeoSyncwebsite. The pMERT (NEST) will be automatically detected by the NeoSyncwebsite, and any necessary software upgrades will be downloaded.

The psychiatrist can then order a number of dosage quotas for aparticular disorder from the website, such as 15 20-minute therapytreatment, one per day, to treat depression. An encrypted key will bedownloaded to the pMERT (NEST), which will be set to allow the dosagequotas requested by the psychiatrist. Once this occurs, the psychiatristwill automatically be billed based on the number and type of dosagequotas. The psychiatrist will then bill the patient (or eventually thepatient's insurance) for the procedure. The patient can take the pMERT(NEST) device to his/her home to use the device in accordance with thetherapy prescribed by the psychiatrist or the patient can be treated inthe psychiatrist's office.

Once the patient has used up all the dosage quotas the psychiatrist hasloaded onto the device, the patient returns to the psychiatrist with thepMERT (NEST) device. The psychiatrist will connect the pMERT (NEST)device to the PC via a USB cable and will login to the NeoSync websiteas before. The website will detect the pMERT (NEST) and will upload alltreatment information. A report can be generated with this information,giving the psychiatrist a quantitative indication of progress. Thereport can include for each treatment the date, start time, end time,initial EEG alpha parameters (i.e., power and Q-factor), and the finalEEG alpha parameters. The psychiatrist can print the report or save itto a file to be placed in the patient's record. At this point, thepsychiatrist can clear the memory of the device and use it for anotherpatient or he/she can order more dosage quotas for the current patient.

If the psychiatrist decides that the patient should use the pMERT (NEST)for a longer period, the psychiatrist can set up an account for thepatient with NeoSync, Inc. This way, the patient is able to order moredosage quotas without returning to the psychiatrist. Only the dosagequotas approved by the psychiatrist will be allowed for the patient toorder. The patient can pay NeoSync directly with a credit card or(eventually) insurance. For each session, the psychiatrist may also bepaid. The psychiatrist would have access to all reports uploaded fromthe pMERT (NEST) via the website.

Example 6

Each patient admitted to the study is randomly assigned into one of thetwo study groups based on treatment using a plugged pMERT (NEST) deviceand sham, where a pMERT (NEST) device rotates a non-magnetic metal blockinstead of a magnet. Patients are kept blind to the treatment condition.Each treatment consists of 22 daily sessions during a 30-day period(and/or at least 10 sessions during a 2 week period or more). Patients'current antipsychotic treatments are kept unchanged during the study.

EEG data during treatments are recorded and individualized according tothe alpha EEG intrinsic frequency (8-13 Hz). The precision of thestimulus rate can be refined to the level of 10% of a hertz. It isdetermined on each patient's average alpha frequency, obtained from 3central EEG leads (C3, C4, and Cz). EEG data during treatments arerecorded from each subject in a supine position with their eyes closedthroughout the testing period. Nineteen EEG electrodes (Ag—Ag Cl) areused according to the International 10-20 system and referenced tolinked mastoids. Electrooculograms (EOGs) from the outer canthus of botheyes are recorded simultaneously to monitor eye movements. At least twominutes of EEG epochs are collected and digitized by a 12-bit A/D(analog/digital) converter at the rate of 200 Hz by a Cadwell EZ IIacquisition system. Sixty seconds of artifact free epochs are utilizedfor fast Fourier transformations (FFT). FFT window is set at 512 datapoints with 80% overlap.

Severity of psychosis, depression, and movement disorders are assessedwith the Hamilton Anxiety Scale (HAMA), the Hamilton Depression Scale(HAMD), PANSS, Montgomery-Asberg Depression Rating Scale (MADRS), BarnesAkathisia Rating Scale (BARS), and Simpson-Angus Scale (SAS),respectively. All rating scales and EEGs are administered at screening,baseline (immediately prior to first treatment), immediately followingthe fifth and tenth treatments.

While the technician administering the pMERT (NEST) device cannot beblinded, the evaluating physicians and EEG technicians remain unaware ofthe type of treatment throughout the duration of study. A prioricategorical definition for clinical response is >30% baseline-to-posttreatment reduction at the end of treatment on PANSS negative symptomsubscale.

Patients with a baseline and at least 1 additional set of completedassessments (at least 5 treatment sessions) are included in the analysisof mean treatment effect. Efficacy in clinical ratings is evaluated byusing analyses of variance (ANOVA) with repeated measure over time. Themodels include 2 between-subject factors of treatment and location, and1 within-subject factors of time. Effect of concomitant antipsychotictreatment can be tested based on the categorization of typical andatypical neuroleptic medications. Grouping differences of all othermeasures are tested individually using the same statistical model. Usinga predefined response criterion, a contingent table analysis can be usedto test the group difference in responding rate.

Raw EEG data are edited offline by an experienced technician who isblind to the treatment conditions to eliminate any significant (>3_arc)eye movements or any other type of apparent artifact. Ten to twenty-fourartifact-free epochs (1,024 data points per epoch) in each recordingchannel are calculated by a fast Fourier transform (FFT) routine toproduce a power spectrum with 0.2 Hz frequency resolution. The intrinsicfrequency of alpha EEG is defined as the mean peak frequency (Fp) of 3central leads (C3, C4, and Cz). EEG variables used in the analysisincluded power density (Pwr), peak frequency (Fp), Fp longitudinalcoherence, and frequency selectivity (Q). See Jin Y et al. Alpha EEGpredicts visual reaction time. Int J Neurosci. 116: 1035-44 (2006),which is incorporated by reference in its entirety.

Coherence analysis is carried out between Fz and Pz in the peak alphafrequency. Recording from Cz is chosen to calculate the Q-factor (peakfreq/half-power bandwidth), a measure of the alpha frequencyselectivity. It is measured in the frequency domain by using a 60 secartifact free EEG epoch and a 2,048 data point FFT with a 10-pointsmooth procedure. Multivariate analysis of variance (MANOVA) across allchannels for each variable is performed to test the treatment andstimulus location effects. Change score for each variable before andafter pMERT (NEST) treatment is used to correlate with the change scoreof each clinical measure from the same time points.

FIG. 12 shows an example of the Q-factor as used in this invention. Thefigure shows a sample graph of the frequency distribution of the energyof an EEG signal. It can be seen that a frequency range, Δf can bedefined as the frequency bandwidth for which the energy is aboveone-half the peak energy. The frequency f₀ is defined as the intrinsicfrequency in the specified band. The Q-factor is defined as the ratio off₀/Δf. As can be seen, when ΔF decreases for a given f₀, the Q-factorwill increase. This can occur when the peak energy E_(max) of the signalincreases or when the bandwidth of the EEG signal decreases.

Example 7 Effect of NEST Device Lowering Blood Pressure

An effect of use of a NEST (i.e. pMERT) device using a method providedherein was shown to lower blood pressure in a female patient. Thepatient, originally using a NEST to treat anxiety, complained of amoderate tension headache and her blood pressure was taken, and read at110/90 mmHg A NEST device was set at a fixed specified frequency equalto an intrinsic frequency within her alpha EEG band and the magneticfield emanating from the device was applied to the patient's head(cerebral cortex). During treatment using the NEST device, threeconsecutive blood pressure measurements were taken at ten minuteintervals, showing 110/85 mmHg, 100/82 mmHg, and 100/70 mmHg,respectively. An hour after treatment with the NEST device had ceased,the patient's tension headache returned, and her blood pressure wasmeasured, reading 110/90 mmHg.

Example 8

In particular embodiments, a single cylindrical magnet that isdiametrically magnetized (pole on the left and right sides of thecylinder) spins about the cylinder axis. The magnet can be placedanywhere around the patient's head, and locations can be chosen based onthe desire for a more focal therapy at a particular location.Alternative embodiments can include stringing two or more cylindricalmagnets together on the same shaft, or along different shafts, to spinthe magnets in unison to create a particular magnetic field in treatingthe patient. A non-limiting examples of this are found in FIGS. 13through 15.

FIG. 16 shows an example embodiment of a NEST device having threediametrically magnetized cylindrical magnets 1602 a, 1602 b, 1602 crotating about their cylinder axes and applied to a subject 1606. Thepoles of each the magnets 1602 a, 1602 b, 1602 c of the shown device arealigned generally to provide a peak magnetic field to the subject 1606that is coincident with the peak magnetic fields delivered to thesubject 1606 from each of the other magnets 1602 a, 1602 b, 1602 c.Another way of saying this is that each of the magnets 1602 a, 1602 b,1602 c has a neutral plane indicated by the dotted line on each ofmagnets 1602 a, 1602 b, and 1602 c, and each the neutral planes isaligned to be generally parallel to the scalp of the subject 1606. Thisconfiguration provides a more uniform field to the subject 1606 than ifthe magnets 1602 a, 1602 b, 1602 c are not aligned in such a manner.

FIG. 17 shows an example embodiment of a NEST device 1788 having threediametrically magnetized cylindrical magnets 1702 a, 1702 b, 1702 cconfigured to rotate about their cylinder axes (not shown). Each of themagnets 1702 a, 1702 b, 1702 c of this example embodiment is coupled toat least one magnet drive pulley 1716 a, 1716 b, 1716 c, 1716 d. Each ofthe magnet drive pulleys 1716 a, 1716 b, 1716 c, 1716 d has at least onedrive belt 1718 a, 1718 b, 1718 c, 1718 d wrapped at least partiallyabout it. The device 1788 also comprises two tensioner assemblies 1708a, 1708 b, each comprising a tensioner block 1710 a, 1710 b, a tensionerarm 1712 a, 1712 b, and at least one tensioner drive pulley 1714 a, 1714b, 1714 c each rotating about an axis going through the tensioner arm1712 a, 1712 b, respectively, the axis generally being parallel to therotation axis of the magnets and to the drive shaft 1704 of the device1788. In the embodiment shown in FIG. 17, each of the tensionerassemblies has two tensioner drive pulleys 1714 a, 1714 b, 1714 c, (onetensioner drive pulley of tensioner assembly 1708 is not shown in FIG.17—obscured by the side support 1722, but can be seen, for example, inFIG. 18). The drive belts 1718 a, 1718 b, 1718 c, 1718 d are each alsowrapped at least partially about at least one tensioner drive pulley1714 a, 1714 b, 1714 c, (one tensioner drive pulley of tensionerassembly 1708 is not shown in FIG. 17—obscured by the side support1722), such that each the drive belts 1718 a, 1718 b, 1718 c, 1718 d iswrapped at least partially around at least one of the magnet drivepulleys 1716 a, 1716 b, 1716 c, 1716 d and is also wrapped at leastpartially around at least one of the tensioner drive pulleys 1714 a,1714 b, 1714 c, (one tensioner drive pulley of tensioner assembly 1708is not shown in FIG. 17—obscured by the side support 1722, but can beseen, for example, in FIG. 18) of the tensioner subassemblys 1708 a,1708 b.

The device 1788 shown in FIG. 17 is held together by two side supports1722, 1720 connected by a support column 1724 a. In some embodiments, asecond support column 1724 b, a third support column (not shown) mayalso connect the side supports 1722, 1720. Each of the tensionerassemblies 1708 a, 1708 b and each of the magnets 1702 a, 1702 b, 1702 care mounted to (coupled to) at least one of these supports, if not boththe side supports 1722, 1720. Each of the magnets 1702 a, 1702 b, 1702 care rotatably mounted to at least one of the side supports 1722, 1720,such that each of the magnets 1702 a, 1702 b, 1702 c can rotate abouttheir rotation axes (cylinder axes) without motion of either of the sidesupports 1722, 1720. Likewise, at least the tensioner drive pulleys 1714a, 1714 b, 1714 c, (and one tensioner drive pulley unshown in FIG. 17)of the tensioner assemblies 1708 a, 1708 b are rotatably mounted(coupled) to at least one of the side supports 1722, 1720, such thateach of the tensioner drive pulleys 1714 a, 1714 b, 1714 c, (and onetensioner drive pulley unshown in FIG. 17) can rotate about theirrotation axes (not shown) without motion of the side supports 1722,1720.

For example, drive belt 1718 a wraps at least partially around themagnet drive pulley 1716 a of magnet 1702 a, and also wraps at leastpartially around the tensioner drive pulley 1714 a of the firsttensioner assembly 1708 a. The drive shaft 1704, coupled to a motor (notshown), drives the rotation of all of the magnets 1702 a, 1702 b, 1702 cof the shown device 1788. The drive shaft 1704 is coupled to a firstmagnet 1702 a which, through its magnet drive pulley 1716 a andassociated belt 1718 a turns the first tensioner drive pulley 1714 a ofthe first tensioner assembly 1708 a. The first tensioner drive pulley1714 a of the first tensioner assembly 1708 a is coupled to the secondtensioner pulley (not shown obscured by side support 1722) of the firsttensioner assembly 1708 a, and, thus, when the first tensioner pulley1714 a is turned by the first drive belt 1718 a, the second tensionerpulley (not shown) is also turned. Since the second drive belt 1718 b iswrapped at least partially around the second tensioner pulley (notshown) as well as the second magnet drive pulley 1716 b of the secondmagnet 1702 b, the motion of the second tensioner pulley (not shown)moves the second drive belt 1718 b and likewise drives the rotation ofthe second magnet 1702 b. The second magnet 1702 has a third magnetdrive pulley 1716 c which is coupled to the second drive pulley 1716 b,and the third drive belt 1718 c wraps at least partially around thethird magnet drive pulley 1716 c, thus, motion of the second drive belt1718 b also causes motion of the third drive belt 1718 c wrapped atleast partially around the third magnet drive pulley 1716 c. The motionof the third drive belt 1718 c, also wrapped at least partially aroundthe third tensioner pulley 1714 b of the second tensioner assembly 1708b thus drives the rotation of the fourth tensioner pulley 1714 c of thesecond tensioner assembly 1708 b which is coupled to the third tensionerpulley 1714 b of the second tensioner assembly 1708 b. Furthermore,since the fourth drive belt 1718 d is wrapped at least partially aroundthe fourth tensioner pulley 1714 c of the second tensioner assembly 1708b, and is also wrapped at least partially around the fourth magnetpulley 1716 d of the third magnet 1702 c, the motion of the fourth drivebelt 1718 d drives the rotation of the third magnet 1702 csimultaneously with the rotation of the other two magnets 1702 a, 1702b.

In an alternative embodiment, the tensioner assemblies are not present,and the drive shaft drives the magnets connected only to each otherusing drive belts. In an alternative embodiment, only one tensionerassembly is present and is coupled to at least two magnets. In analternative embodiment, only one tensioner assembly is present and iscoupled to each of the magnets. In an alternative embodiment, themagnets are coupled to each other by gears. In an alternativeembodiment, the magnets are coupled to each other by a combination of atleast one gear and at least one belt. In an alternative embodiment, themagnets are coupled to each other by a combination of at least one gearand at least two belts, wherein each belt is coupled to a tensionerassembly as generally described herein. In an alternative embodiment,the magnets are coupled to each other by a rotation means, wherein therotation means is configured to drive the rotation of the magnetssimultaneously.

The tensioner assemblies in the embodiments shown in FIG. 17, FIG. 18,and FIG. 19, for non-limiting example, are configured to keep the drivebelts taut during use and, therefore, ensure that the rotation of themagnets is simultaneous and generally in-phase as applied to the subjectwhere the magnets are aligned such that each of the neutral planes ofeach of the three magnets are generally aligned to be parallel to thescalp of the subject.

FIG. 18 depicts an exploded view of the example embodiment of the NESTdevice 1888 of FIG. 17 having three diametrically magnetized cylindricalmagnets configured to rotate about their cylinder axes. Shown in FIG. 18is a NEST device 1888 having two tensioner assemblies 1808 a, 1808 b.Tensioner assembly 1808 a comprises a tensioner block 1810 a thatcouples to the side support 1822 by at least one tensioner dowel pin1832 a. The tensioner block 1810 a also couples to the side support 1820by at least one tensioner dowel pin 1832 b. The tensioner block 1810 afloats freely along at least a portion of the dowel pins 1832 a, 1832 b.The tensioner block 1810 a is attached to a tensioner arm 1812 a whichhas two tensioner drive pulleys 1814 a, 1814 d, which couple to drivebelts 1818 a, 1818 b (respectively) which themselves are coupled tomagnets 1802 a, 1802 b (respectively) of the device 1888 through magnetdrive pulleys 1816 a, 1816 b. The tensioner block 1810 a exerts a forceon the belts 1818 a, 1818 b to keep the belts taut during use, since thetensioner block 1810 a is also coupled to tensioner springs 1830 a, 1830b which push the tensioner block 1810 a away from the side supports1822, 1820, and thus, away from the magnet drive pulleys 1816 a, 1816 bcoupled to the side supports 1822, 1820 by center pins (not shown) thatrun through each of the drive pulleys 1816 a, 1816 b and the magnets1802 a, 1802 b. When the center pin is also attached to a motor, it mayalso rotate the magnet and its associated magnet drive pulley(s), and itmay be called a drive shaft. Nevertheless, the magnet drive pulleys 1816a, 1816 b can rotate, and with their rotational movement the magnetdrive pulleys 1816 a, 1816 b can rotate, or be rotated by, the magnets1802 a, 1802 b.

Likewise, tensioner assembly 1808 b comprises a tensioner block 1810 bthat couples to the side support 1822 by at least one tensioner dowelpin 1832 c. The tensioner block 1810 b also couples to the side support1820 by at least one tensioner dowel pin 1832 c. The tensioner block1810 b floats freely along at least a portion of the dowel pins 1832 c,1832 d. The tensioner block 1810 b is attached to a tensioner arm 1812 bwhich has two tensioner drive pulleys 1814 b, 1814 c, which couple todrive belts 1818 d, 1818 c (not shown) (respectively) which themselvesare coupled to magnets 1802 b, 1802 c(respectively) of the device 1888through the magnet drive pulleys 1816 c, 1816 d. The tensioner block1810 b exerts a force on the belts 1818 d, 1818 c (not shown) to keepthe belts taut during use, since the tensioner block 1810 b is alsocoupled to tensioner springs 1830 c, 1830 d which push the tensionerblock 1810 b away from the side supports 1822, 1820, and thus, away fromthe magnet drive pulleys 1816 c, 1816 d coupled to the side supports1822, 1820 by center pins (not shown) that run through each of the drivepulleys 1816 c, 1816 d and the magnets 1802 b, 1802 c. When the centerpin is also attached to a motor, it may also rotate the magnet(s) andits associated magnet drive pulley(s), and it may be called a driveshaft. Nevertheless, the magnet drive pulleys 1816 c, 1816 d can rotate,and with their rotational movement the magnet drive pulleys 1816 c, 1816d can rotate, or be rotated by, the magnets 1802 b, 1802 c.

Also shown in FIG. 18 are support screws 1826 a, 1826 b which attach thesupport columns 1824 b (other support columns are either not called-outor not shown in FIG. 18) to the side support 1822 and/or to the sidesupport 1820.

FIG. 19 shows the example NEST device embodiment of FIG. 17 and/or ofFIG. 18 having three diametrically magnetized cylindrical magnets 1902a, 1902 b, 1902 c configured to rotate about their cylinder axes andincluding a frame 1934 and base 1936 for mounting the NEST device. Theembodiment shown in FIG. 19 includes a NEST device having three magnets1902 a, 1902 b, 1902 c, each having magnet drive pulleys 1916 a, 1916 b,1916 c, 1916 d at least partially about which is wrapped a drive belt1918 a, 1918 b, 1918 c, 1918 d each of which is also at least partiallywrapped around a tensioner drive pulley 1914 a, 1914 b (not shown) 1914c (not shown) 1914 d (not shown) coupled to a tensioner arm 1912 a, 1912b (not shown) of a tensioner assembly. Each tensioner assembly mayinclude a tensioner block 1910 a (not shown) 1910 b, and a tensionerspring 1930 a (not shown), 1930 c which cooperate with at least one ofthe side supports 1922, 1920 to pull the drive belts 1918 a, 1918 b,1918 c, 1918 d taut. The magnets 1902 a, 1902 b, 1902 c are rotatablycoupled to side supports 1922, 1920, and at least one magnet 1902 a inthe embodiment shown is coupled to a drive shaft 1904 which rotates themagnet 1902 a to which it is directly coupled, and through thecooperation of the magnet drive pulleys 1916 a, 1916 b, 1916 c, 1916 d,drive belts 1918 a, 1918 b, 1918 c, 1918 d, and tensioner drive pulleys914 a, 1914 b (not shown) 1914 c (not shown) 1914 d (not shown), alsorotates the other magnets 1902 b, 1902 c of the NEST device such thatall of the magnets 1902 a, 1902 b, 1902 c rotate simultaneously.

FIG. 20 shows an example embodiment of a NEST device having eightdiametrically magnetized cylindrical magnets 2002 a-2002 h, configuredto rotate about their cylinder axes. Each of the magnets 2002 a-2002 hhas at least one magnet drive pulley 2016 a-2016 n coupled to it whichrotates the magnet 2002 a-2002 h when the magnet drive pulley 2016a-2016 n is rotated by a belt 2018 a-2018 h that is at least partiallywrapped around at least one of the magnet drive pulleys 2016 a-2016 n.In the embodiment shown, a drive shaft 2004 has two drive belts 2018 d,2018 e wrapped at least partially around the drive shaft 2004. The driveshaft 2004 thus rotates all of the magnets 2002 a-2002 h simultaneouslythrough a series of drive belts 2018 a-2018 h and magnet drive pulleys2016 a-2016 n all coupled to the drive shaft 2004.

For example, the first drive belt 2018 e is wrapped at least partiallyaround the drive shaft 2004, and is also wrapped at least partiallyaround a first magnet drive pulley 2016 h of a first magnet 2002 e. Asecond drive belt 2018 f is wrapped at least partially around a secondmagnet drive pulley 2016 i of the first magnet 2002 e. The second drivebelt 2018 f is also wrapped at least partially around a third magnetdrive pulley 2016 j of the second magnet 2002 f. A third drive belt 2018g is wrapped at least partially around a fourth magnet drive pulley 2016k of the second magnet 2002 f. The third drive belt 2018 g is alsowrapped at least partially around a fifth magnet drive pulley 2016 l ofa third magnet 2002 g. A fourth drive belt 2018 h is wrapped at leastpartially around a sixth magnet drive pulley 2016 m of the third magnet2002 g. The fourth drive belt 2018 h is also wrapped at least partiallyaround a seventh magnet drive pulley 2016 n of a fourth magnet 2002 h.As arranged, therefore, the motion of the first drive belt 2018 ecoupled to the drive shaft 2004 rotates the first magnet 2002 e, thesecond magnet 2002 f, the third magnet 2002 g, and the fourth magnet2002 h simultaneously.

Similarly, the fifth drive belt 2018 d is wrapped at least partiallyaround the drive shaft 2004, and is also wrapped at least partiallyaround an eighth magnet drive pulley 2016 g of a fifth magnet 2002 d. Asixth drive belt 2018 c is wrapped at least partially around a ninthmagnet drive pulley 2016 f of the fifth magnet 2002 d. The sixth drivebelt 2018 c is also wrapped at least partially around a tenth magnetdrive pulley 2016 e of the sixth magnet 2002 c. A seventh drive belt2018 b is wrapped at least partially around an eleventh magnet drivepulley 2016 d of the sixth magnet 2002 c. The seventh drive belt 2018 bis also wrapped at least partially around a twelfth magnet drive pulley2016 c of a seventh magnet 2002 b. An eighth drive belt 2018 a iswrapped at least partially around a thirteenth magnet drive pulley 2016b of the seventh magnet 2002 b. The eighth drive belt 2018 a is alsowrapped at least partially around a fourteenth magnet drive pulley 2016a of an eighth magnet 2002 a. As arranged, therefore, the motion of thefifth drive belt 2018 d coupled to the drive shaft 2004 rotates thefifth magnet 2002 d, the sixth magnet 2002 c, the seventh magnet 2002 b,and the eighth magnet 2002 a simultaneously. In an alternativeembodiment, the drive shaft has only one drive belt that drives all ofthe rotation of all of the magnets. Also shown in FIG. 20 are the sidesupports 2022, 2020 connected by at least two support columns 2024 a,2024 b. The supports 2020, 2022 hold each of the magnets 2002 a-2002 hin place relative to the supports 2020, 2022 while allowing rotationalmotion of the magnets 2002 a-2002 h and of the drive shaft 2004 whichmay me driven, for non-limiting example, by a motor (not shown).

FIG. 21 shows the magnet rotation of the example NEST device embodimentof FIG. 20 having eight diametrically magnetized cylindrical magnets2102 a-2102 h configured to rotate about their cylinder axes. FIG. 21shows a side view of an embodiment of a NEST device (not showing, forexample, side supports), which is similar to the embodiment shown inFIG. 20. In this embodiment, each of the magnets 2102 a-2102 h has atleast two drive belts (for example, drive belts 2118 a-2118 h) coupledto it which rotate the magnet 2102 a-2102 h, or which are rotated by themagnet 2102 a-2102 h, when the drive shaft 2104 is rotated. In theembodiment shown, two drive belts 2118 d, 2118 e are wrapped at leastpartially around the drive shaft 2104. The drive shaft 2104 thus rotatesall of the magnets 2102 a-2102 h simultaneously through a series ofdrive belts 2118 a-2118 h all coupled to the drive shaft 2104. Shown inthis embodiment is an example of the direction of rotation of themagnets 2102 a-2102 h (indicated by arrows) resulting from a clockwiserotation of the drive shaft 2104. An opposite direction of movement isachieved when the drive shaft is rotated in a counter-clockwisedirection. In the embodiment shown, the clockwise rotation of the driveshaft 2104 rotates all of the magnets 2102 a-2102 h in a clockwisedirection due to the belt 2118 a-2118 h arrangement shown. Each of thebelts 2118 a-2118 h shown is wrapped either around two magnets or arounda magnet and the drive shaft.

Example 10

In particular embodiments, a disc shaped magnet that is axiallymagnetized (the poles are on the top and bottom faces) can be cut inhalf, one half turned over (aligning N of one half with S of the otherhalf) and placed together. This disc can be spun about the center of thedisc to get a magnetic field that is uniform over a large area. In asimilar embodiment, two rectangular magnets having poles aligned andpositioned similarly to the disc as previously described can be spunabout the center of the rectangular magnets to create a similarlyuniform field. An example of the disc magnet is shown in FIG. 22, and anexample of the rectangular magnet similar to the disc magnet is shown inFIG. 23.

FIG. 22 shows an example embodiment of a NEST device having two discmagnets 2202 a, 2202 b that rotate about a common rotation axis 2236.The device comprises two disc shaped magnets 2202 a, 2202 b that areaxially magnetized (the poles are on the top and bottom faces). Thenorth pole of the first magnet 2202 a aligns with the south pole of thesecond magnet 2202 b (aligning their neutral planes). The device furthercomprises a drive shaft 2204 that aligns with the center of the discmagnets 2202 a, 2202 b and with, therefore, the rotation axis 2236 ofthe magnets 2202 a, 2202 b.

FIG. 23 shows an exploded view of an alternate embodiment of an exampleNEST device embodiment similar to that of FIG. 22 having two rectangularmagnets 2302 a, 2302 b that rotate around a common rotation axis 2336.The device comprises two rectangular magnets 2302 a, 2302 b that aremagnetized such that the north pole of the first magnet 2302 a facesaway from the drive shaft 2304, and the south pole of the first magnet2302 a faces the drive shaft 2304, and the north pole of the secondmagnet 2302 b faces the drive shaft 2304 while the south pole of thesecond magnet 2302 b faces away from the drive shaft 2304. The poles ofeach of the magnets 2302 a, 2302 b, thus, face the top cover 2352 andthe bottom cover 2350 of the device, but the magnets 2302 a, 2302 b,have opposite polarity. In the embodiment shown, the first magnet 2302 ais held in place in the device by a first magnet holder 2344 a havingtwo pieces that are connected by a magnet holder cap screw 2342 and amagnet holder dowel pin 2340. The first magnet 2302 a is placed betweenand at least partially within the pieces of the first holder 2344 a.Likewise, the second magnet 2302 b is held in place in the device by asecond magnet holder 2344 b having two pieces that are connected by amagnet holder cap screw (not shown) and a magnet holder dowel pin (notshown). The second magnet 2302 b is placed between and at leastpartially within the pieces of the second holder 2344 b. The two holders2344 a, 2344 b are coupled together, and may have a center beam 2348that holds the first and second holders 2344 a, 2344 b together. Theholders 2344 a, 2344 b may also be held together additionally oralternatively by adhesive 2346. The drive shaft 2304 is coupled to theholders 2344 a, 2344 b, in the embodiment shown, by attaching to thecenter beam 2348, which thus couples the magnets 2302 a, 2302 b to thedrive shaft 2304 such that rotation of the drive shaft 2304 likewisespins the magnets 2302 a, 2302 b within the holders 2344 a, 2344 b aboutthe rotation axis 2336. The drive shaft 2304 may alternatively and/oradditionally be coupled to the holders 2344 a, 2344 b and to the centerbeam 2348 by adhesive 2346. The magnets 2302 a, 2302 b encased in theholders 2344 a, 2344 b are additionally housed within a top cover 2352and a bottom cover 2350. The covers 2350, 2352 are connected to oneanother by at least one cover cap screw 2354. The drive shaft 2304 fitsthrough at a hole 2356 in at least one of the covers, for example, thebottom cover 2350. Where the cover 2350 is disc-shaped, as shown in FIG.23, the hole 2356 is located the center of the disc cover 2350, and thehole 2356 is configured such that the drive shaft 2304 may rotate freelywithin the hole 2304, for example, with aid of a bearing which allowsdrive shaft rotation (and, thus, magnet rotation) relative to the covers2350, 2352.

Example 11

FIG. 24 shows an example embodiment of a NEST device similar to theembodiments depicted in FIG. 22 and/or 23 having two magnets 2402 a,2402 b rotating about a common rotation axis applied to a subject 2406and showing the controller subunit 2458 coupled to a drive shaft 2404that rotates the magnets 2402 a, 2402 b. The controller subunit 2458 maycontain a motor (not shown) that cooperates with the drive shaft 2404 torotate the magnets 2402 a, 2402 b.

FIG. 25 shows block diagram of an example embodiment of a NEST deviceshowing example elements of the NEST device and of its controllersubunit. For example the embodiment shown depicts a magnet 2502 that ismounted by a frame 2534 to a base 2536. This allows the magnet 2502 tobe held stationary as the device treats a subject whose head may bepositioned near to the magnet 2502 (within the magnetic field producedby the magnet 2502). The magnet 2502 is coupled to the controllersubunit 2558 by a drive shaft 2504. The drive shaft 2504 may couple to amotor 2572 of the controller subunit 2558 by a coupling 2578. Thecoupling may allow for various magnet arrangements to be interchanged bymerely decoupling the drive shaft from the controller subunit andcoupling a device having another arrangement of magnets (such as, forexample, those described herein). The magnet 2502 may be controlled bythe controller subunit 2558 through the motor 2572 that may be driven bya motor driver 2574. The motor driver 2574 may be coupled (directly orindirectly) to a power supply 2576. The motor driver 2574, which cancontrol, for non-limiting example, the speed, direction, acceleration,etc, of the magnet 2502 through the drive shaft 2504, can be directedand/or monitored by controls such as, for example, a device speedcontrol 2560, an on/off control 2562, a display 2564, arandom/continuous control 2566, and a high/low control 2568. A user canadjust each of these controls, which are coupled to a processor circuitboard 2570 and thus coupled to the motor driver 2574.

Alternatively, and/or additionally, the drive shaft 2504 and/or themagnet(s) may be controlled automatically based on a prescribedtreatment (time of treatment, frequency of magnet rotation, etc) that isdownloaded and/or programmed into the processor circuit board 2570 froma source external or internal to the controller subunit, as previouslydescribed herein. Treatments received may be stored by the controllersubunit. Additionally and/or alternatively, where EEG electrodes arealso present in the device and are capable of measuring the subject'sbrain waves, the device may adjust the treatment automatically by abiofeedback system. Additionally and/or alternatively, where EEGelectrodes are present in the device and are capable of measuring thesubject's brain waves, the treatment may be chosen based on the readingsof the subject's brain waves prior to the treatment. Additionally and/oralternatively, where EEG electrodes are present in the device and arecapable of measuring the subject's brain waves, the treatment may bechosen automatically by the device based on the readings of thesubject's brain waves prior to the treatment and based on a set of rulesstored in the controller subunit. Additionally and/or alternatively,where EEG electrodes are present in the device and are capable ofmeasuring the subject's brain waves, the controller subunit is capableof storing the output of the EEG electrodes prior to, during, and/orafter treatment with the NEST device. Additionally and/or alternatively,where EEG electrodes are present in the device and are capable ofmeasuring the subject's brain waves, the controller subunit is capableof transmitting the output of the EEG electrodes prior to, during,and/or after treatment with the NEST device. This transmitting may bereal-time (during measurement), or after storage of the EEG electrodeoutputs and during an upload or download from the NEST device.

Example 12 Effect of a Device Lowering Blood Pressure

An effect of use of a modified rTMS device according to the methods anddevice descriptions provided herein was shown to reduce the symptoms offibromyalgia. The patient complained of chronic widespread pain andtenderness to light touch, and was diagnosed with fibromyalgia. The NESTdevice was used to tune an intrinsic frequency (of the patient's alphawave). Following treatment, the patient reported a reduction of thesymptoms of fibromyalgia.

Example 13

FIG. 26 shows an example embodiment of a NEST device having a single barmagnet 2602 that moves linearly along its north-south axis 2639 onceeach time the supporting ring (or annulus) 2619 is rotated (rotationshown by arrows in FIG. 26), providing a pulse-type alternating magneticfield at the frequency of rotation. In this embodiment, a magnet 2602 issecured against a rotating ring (or annulus) 2619 with a spring 2628,where the ring 2619 has one or more detents 2629. The subject 2606 isshown below the ring 2619 in FIG. 26. When the ring 2619 is rotated, asshown with the arrows in FIG. 26, the magnet 2602 will be thrust intoeach detent 2629 once per rotation. As the ring 2619 continues torotate, the magnet 2602 will move back to its original position. Thisperiodic thrust may generate a more unipolar pulsatile magnetic fieldthan that generated by a rotating magnet. The width and amplitude of themagnetic pulse depends on the mass and strength of the magnet, as wellas the strength of the spring, and the depth of the detent.

In alternative embodiments to that shown in FIG. 26, there could bemultiple detents in the ring. The ring could be non-circular. The magnetcould rotate around the ring, while the ring is stationary. There couldbe multiple magnets and a single detent. There could be multiple magnetsand multiple detents. Instead of a detent, the magnet or magnets couldencounter a ridge, or multiple ridges. The magnet or magnets couldencounter slopes, rather than sharp detents or ridges. The magnet couldbe positioned such that the north pole is closer to the treatment areathan the south pole, or such that the south pole is closer to thetreatment area than the north pole (such as is shown in FIG. 26). Insome embodiments, the number of detents is the same as the number ofmagnets of the device. In some embodiments, the number of detents is notthe same as the number of magnets of the device. In some embodiments,the number of detents is a multiple of the number of magnets of thedevice. In some embodiments, the number of detents is not a multiple ofthe number of magnets of the device.

In an alternative embodiments of the device, the magnet may flip (orrotate) about an axis between the north pole and south pole as a ringsimilar to that shown in FIG. 26 rotates. The magnet may be freelyrotatable about the axis between the north pole and south pole, and themagnet may be rotatable about a shaft. The shaft, in this embodiment, isnot coupled to a drive source. Rather, the ring itself may drive theflipping (rotating) of the magnet by capturing a first portion of themagnet in a first detent and moving that first portion as the ring movesuntil a second portion of the magnet is captured by second detent of thering which likewise moves the second portion of the magnet. In someembodiments, the first portion is associated with a first pole of themagnet, and the second portion is associated with a second pole of themagnet. In one embodiment, the first pole may be the north pole of themagnet and the second pole may be the south pole of the magnet. Inanother embodiment, the first pole may be the south pole of the magnetand the second pole may be the north pole of the magnet. A drive sourcemay drive the movement of the ring which, in turn, drives the rotationof the magnet. The drive source may be motor, for non-limiting example.

Example 14

FIGS. 31 and 32 show the results of a clinical trial utilizing the NESTdevice and methods for the treatment of depression as provided herein. Adevice was used such as shown in FIG. 19, with permanent magnetsarranged as shown in FIG. 16. In the method used in this trial, amagnetic field was adjusted to influence the Q-factor of an intrinsicfrequency of each subject within the alpha-band. The magnetic field wasapplied close to the head of the subject. EEG readings were taken beforetreatment began. A Cadwell Easy 2.1 EEG system was used to take a19-lead EEG reading. The intrinsic frequency in the alpha band (7-11 Hz)was determined using the initial EEG reading Patients were placed in oneof three groups: constant frequency, random frequency, or sham, withequal probability for each group. Patients received treatment everyweekday for 30 days. EEG readings were taken after treatment at least ona weekly basis. If the patient was in the “constant frequency” group,the NEST was set to rotate the magnets at the intrinsic frequency. Ifthe patient was in the “random frequency” group, the NEST was set torotate the magnets at random frequencies between 6 Hz and 12 Hz,changing frequencies once per second. If the patient was in the “SHAM”group, the magnets in the NEST were replaced with steel cylinders,thereby imparting no magnetic field to a head of the patient. Thepatients in this group were divided into two subgroups with equalprobability, with one group having the cylinders rotated at theintrinsic frequency and the other group having the cylinders rotated atrandom frequencies as noted above. For this clinical trial sixteen (16)subjects received treatment with the NEST device. Eleven (11) subjectsresponded to treatment (i.e. the Responders) and five (5) subjects didnot respond to treatment (i.e. Non-Responders). Eleven (11) patientsreceived treatment with the SHAM device.

FIG. 31 shows the percentage change in HAMD score in subjects beingtreated with the NEST device over the course of four (4) weeks. It isdivided between subjects who responded to treatment (i.e. Responders)and subjects who did not respond to treatment (i.e. Non-Responders).Responders were classified as such when their HAMD scores decreased by50% at least over the course of the four (4) weeks of treatment. Thefirst bar is the average baseline HAMD score. Each subsequent barrepresents the average HAMD score at the end of a week, weeks 1, 2, 3,and 4, left to right, respectively.

FIG. 32 shows the percentage change in HAMD score in subjects beingtreated with the NEST device versus the SHAM device over the course offour (4) weeks, as described in reference to FIG. 31 above. Baseline isnot represented on the graph—it should be assumed to be 0.00. The firstdata point represents the average change after one (1) week oftreatment. The second data point is the average change after two (2)weeks of treatment. The third data point is the average change afterthree (3) weeks of treatment. The fourth data point is the averagechange after four (4) weeks of treatment. The top line represents theaverage HAMD score for subjects treated with the NEST device, the bottomline represents the average HAMD score for subjects treated with theSHAM device.

Example 15

FIG. 33 shows the results of a clinical trial utilizing the NEST devicefor the treatment of anxiety. This trial involved two (2) patients(subjects). Both patients received treatment with the NEST device asshown in FIG. 19, with permanent magnets arranged as shown in FIG. 16.In the method used for these patients, a magnetic field was adjusted toinfluence the Q-factor of an intrinsic frequency of each subject withinthe alpha-band. The magnetic field was applied close to the head of thesubject. EEG readings were taken before treatment began. A Cadwell Easy2.1 EEG system was used to take a 19-lead EEG reading. The intrinsicfrequency in the alpha band (7-11 Hz) was determined using the initialEEG reading. Both patients were treated with a constant frequency,wherein for each patient the NEST was set to rotate the magnets at theintrinsic frequency detected for that patient. Patients receivedtreatment every weekday for 30 days. EEG readings were taken aftertreatment at least on a weekly basis. The first data point is thebaseline HAMA score. The second data point for each line represents theHAMA score after one (1) week of treatment for each patient. The thirddata point for each line represents the HAMA score after two (2) weeksof treatment for each patient. The fourth data point for each linerepresents the HAMA score after four (4) weeks of treatment for eachpatient.
